Arizona Personal Injury Statute of Limitations: Deadlines Explained

You were hurt in a crash, a fall, or a dog bite, and the medical bills are arriving before you feel like yourself again. What many people do not realize is that the Arizona personal injury statute of limitations may already be running, and missing it can end a claim before it starts.
This post explains Arizona's general deadline, the discovery rule, the special deadlines for claims against government, the basics of negligence, and how shared fault affects a recovery. It is written for injured Arizonans and their families who want to understand the rules before giving a statement to an insurance adjuster or deciding whether to call an attorney.
How Long Do You Have to File a Personal Injury Claim in Arizona?
Arizona's general deadline for personal injury claims is two years under A.R.S. § 12-542. This is the core rule behind the Arizona personal injury statute of limitations. The guide is built around this statute and explains what filing actually means.
Deadlines matter because they are strict. A claim filed after the deadline can be lost even if the injury was serious and the other side was clearly at fault. Knowing the deadline early gives you time to understand your options. It also helps you avoid waiting too long while focusing on recovery, which is easy to do after an injury.
How Does the Discovery Rule Affect Personal Injury in Arizona?
The discovery rule can start the clock later in some cases. In general terms, it addresses situations where an injury or its cause is not known right away. The guide explains how the discovery rule works and when it may come into play.
Because the discovery rule depends on specific facts, it is not a safe assumption to make on your own. Relying on it without understanding how it applies can be risky. The guide explains the rule in plain language so you can see why it matters and how it fits with the general two-year deadline.
What Is the Deadline for a Claim Against a Government Agency in Arizona?
Claims against government follow special rules. Arizona has shorter deadlines for these claims than the general two-year rule. People are often surprised by this, especially after an injury involving a public road, vehicle, or property.
The guide explains these special, shorter deadlines for government claims. Because they move faster than the general rule, understanding them early is especially important. If a government vehicle, road, or building may be involved, that fact alone is worth noting right away.
What Do You Need to Prove in an Arizona Negligence Claim?
Most personal injury claims are based on negligence. The guide explains negligence in plain terms, broken into four parts. Each part must be shown for a claim to succeed.
Thinking through these parts one at a time helps you see where a claim is strong and where questions remain. Insurance adjusters often focus on the same elements. The four parts are:
Duty of care
Breach of that duty
Causation
Damages
How Does the Arizona Comparative Negligence Rule Work?
Accidents often involve more than one person's mistakes. Arizona's comparative negligence rule can reduce a recovery when more than one person shares fault. Understanding this rule helps explain why the question of who did what can matter so much. It is also why careful, accurate statements about an accident are important.
The guide also covers the kinds of cases people bring and how to protect a recovery. Topics include:
Car accident claims and the Arizona deadline
Slip-and-fall claims in Arizona
Dog bite claims in Arizona
How to maximize and protect your recovery
Why the Arizona Personal Injury Statute of Limitations Matters Early
Early organization can make a real difference. Keeping medical records, bills, photos, and a written account of what happened gives you a clearer picture of the claim. It also helps before you give a statement to an insurance adjuster. Writing things down soon after an accident matters, because details fade over time.
